Why don't you just buy one made for a pressure washer

Then buy a 1/4" NPT to garden hose adapter, but I think you'll find that a
garden hose doesn't have enough pressure. In which case, you can buy a 1/4"
NPT to quick connect adapter and put it on a pressure washer. If you don't
have access to a pressure washer, then just buy a Drain King.

Professional plumbers clean sewer pipes with a jetter -- special pressure
washer with a nozzle that spray the water backwards (to propel the hose
forward) and forward (to puncture the dirt in front).

For home owners, is there a similar nozzle for a garden hose that would
allow me to clean storm drains? If not, is there something like a metallic
dome cover for hose end that I can drill holes in to make one myself?
